Abstract

The upgraded design of the plasma chamber (PC) and of the first wall (FW) system consider the updated scenarios for IGNITOR vertical plasma disruption (VDE). The electromagnetic (EM) loads are so large to require a dynamic elastic-plastic structural analysis of the PC. A 360deg PC torus has been modeled to take into account the toroidal asymmetry of the halo current as well as the lateral EM loads. The PC wall thickness reduces the displacements within the clearance with toroidal coil. The PC low-cycle fatigue analysis results in a lifetime longer than the number of disruption events at the maximum performance
